Building a Hash Table from Scratch

This lesson is about how hash tables are implemented in JavaScript.

Hash Table Using Bucket Chaining

We will use the chaining strategy along with the resize operation to avoid collisions in the table.

All elements with the same hash key will be stored in an array at that index. In data structures, these arrays are called buckets. The size of the hash table is set as n*m where n is the number of keys it can hold, and m is the number of slots each bucket contains. Each slot holds a key/value pair.
